13 Claims. (Cl. 100-31) My invention relates to an improved method a fortying and binding bale ties, wires and the like securely into bundles.

More particularly, my invention contemplates 5 assembling the bale tiesto be bundled and winding about them a tie wire in such manner as tosecurely hold the ties in dense compact cylindrical form-with the endsof the tie wire so anchored as to, prevent any slippage that might 10loosen its coils and slacken its hold on the bundle. A further important object of my invention is to subject the loose bundle ofties to arotating action about their long axis applied from one end of the bundleand adapted to produce a twist 15 in the bundled wires before they arebound, the advantage of this being that it will draw the bale ties intoa more compact cylindrical mass and by giving a twist to.all the tiesthat increases in degree from the axis outwardly so that the outer onesthat are exposed having less tendency to pull or work loose under thebinding wire as a result of handling, a better bundle results and onemuch safer .to handle.

A- further feature of my invention is to feed the binder wire undertension along the bundle while providing a moving stop or guide meansagainst which the binder wire can draw the rotating bundle to insure itstight application.

My invention further contemplates a method 30 for the production of animproved bundle in which the ends of the tie wire are. anchored by beingdrawn transversely of, and interlocked with, the ends of the bundle ofbale ties so that the coils of the tie wire cannot slip or loosen.

This method of bundling is important because, 'to obtain the tightestpossible bundle, it is essential to bring the bale ties compactly intocylindrical shape and then to tightly apply the binding coils of wirethereto and finally to so anchor 40 both ends of the binding wire thatits coils cannot slip and loosen their grip on the bundle,

thereby permitting the latter to flatten out.

When the bale ties in the bundle for any reason become loosened,handling will cause them to be 45 pulled loose from the bundle withresultant loss in stock and frequent injury to the men handling thebundles.

More particularly my invention contemplates anchoring the ends of thetie wire by passing 50 them transversely across the ends of the bundle,

the tag bearing end of the tie wire being preferably applied outside ofthe canvas wrapping usually applied to the loop ends of the bale ties,and the other end of the tie wire is anchored by 55 being drawn betweenthe other ends of the bale ties beyond the final tie coils and beforethe application of the binding canvas.

My invention embodies further novel features and details of constructionhereinafter more particularly described and claimed, reference beingmade to the accompanying drawings wherein;

Referring now to the drawings for a better understanding of myinvention, I show a base 6 on one end of which is mounted a headstock'I. A chuck 8, which may be of any suitable type and operated in anysuitable manner such as by air or'electricity, is mounted for rotationon the headstock to receive one end of a bundle of bale ties 9. Thechuck 8 is driven by a pulley Ill from a motor. I I through suitablereduction gears (not shown) provided within the headstock.

A carriage I2 is employed to guide the binding wire l3 onto the bundle 9and is provided with rollers 14 for movement along the tracks I6. Thecarriage is drawn back and forth along the tracks I 6 by an endlesscable I! which engages a bracket [8 provided on the underside of thecarriage. The cable is passed around loose pulleys l9 and 2| mounted atthe ends of the base 6 and then downwardly around loose pulleys 22 and23 mounted at the center of the machine for engagement with a cable drum24, (see Figs. 2 and 3). The drum 24 is mounted for rotation on a stand26 and is driven by a reversible motor 21 through a worm 28 and a wormgear 29.

A plurality of loose pulleys 33 are mounted on the top 31 of thecarriage I2 for engagement with the binding wire l3 and are adjustablymounted in slots 32 (see Fig. 5) in order that the desired tension canbe placed on the binding wire throughout the winding operation. Thebinding wire passes from the tension pulleys through an eye bracket 33and under a, hook guide 34for engagement with the bundle. The guide 34is secured to a holddown arm 36 which is pivotally mounted on thecarriage top at 31 and provided with a transversely arcuate foot 39 forengagement with the bundle as a holddown means therefor during thebundle tying operation.

A bundle support plate or apron 39 is secured to the base of the machineby brackets 4| and has its side edges upturned to form flanges 42 and43. A plurality of arms 44 are mounted on a rocker shaft 45 journaledbelow the plate. 39 and then project up through slots 46 in the plate tohold the bundle in position.throughout the binding operation, afterwhich they are lowered to permit the wrapped bundle to roll down theplate and into the trough formed by the flange 43. A push rod 41 isemployed to rock shaft 45 and raise and lower the arms 44 and it isprovided with a boss 48 for engagement with a bracket 49 when it isdesired to hold the arms 44 in their upright or operating position.

The motor ii is controlled by a switch 5! which is adapted to beactuated by a control rod 52 slidably mounted in bearing brackets 53. Aswitch 54 (Fig. 2) is mounted below the switch 5! and actuated byacontrol rod 56, mounted to slide in brackets 51, to start, stop, andreverse the motor 21. An arm 53 is secured on the carriage l2 forengagement with a collar 59 on rod 56 to throw the switch 54 which isadapted to stop the motor upon the return of the carriage to its initialstarting position. Other automatic stop means may be advantageouslyemployed where the length of the bundles does not vary, for example,such as would stop the carriage at the completion. of the windingoperation illustrated in Fig. 6.

In tying a bundle of wires in accordance with my improved method, acanvas cap 6| is first placed over the eye bearing ends of the bale tiesforming the bundle 9 and a metal information tag 62 -is provided with asmall opening by which it is strung onto the end of the binding wire I3.The end portion 63 of the binding wire is then placed within the capafter which the wire is bent back and drawn tightly across the end ofthe bundle at 64 and returned along the opposite side of the cap fromthe portion 63- (see Fig. 6). The capped end of the bundle is thenmounted between the chuck jaws 64 with the bundle resting freely on theplate 39 between its flange 42 and the arms 44.

The winding operation is started by throwing the switch 5| to cause themotor H to revolve the chuck, and the switch 54 is thrown to start themotor 21 which causes the carriage l2 to move on its wheel supportsalong the tracks "5 towards the free end of the bundle. The motors IIand 21 are so controlled as to form several initial turns 66 of thebinding wire about the cap GI and wire end 63 thereby fixedly securingthe end 63 of the binding wire in position, after which the motors areoperated to form the spiral windings 61, the pitch of which iscontrolled by the rate of carriage feed. The foot 38 on the arm 36serves to hold the rotating bundle of ties 9 againstthe upward pullapplied thereon by the tension on wire l3 as it is wound about thebundle. As the carriage approaches the free end of the bundle the switch54 is thrown to stop the carriage, after which the rotation of thebundle will form the closely wound turns 68 and the switch 5i is thenthrown to stop the rotation of the chuck.

The binding wire I3 is then cut to leave an end portion 69 (Fig. 6)which is drawn in between the ends of the ties 9 at H and is drawn underand then bent back over the turns 68 at 72, see Fig. 7. The chuck jawsare released and the arms 44 are lowered to permit the bundle to rolldownthe plate 39 into the trough formed by the flange 43 where a cap 79is secured on the end of the bundle by means of wires 13 (see Fig. 8).

It will be observed readily that the wires making up the bundle of tiesare left loose at one end and therefore when the rotation of the bundlecommences they will readily and freely set 'themselves in a twist whichis increased by the drag imposed tangentially (see Fig. 2) on the bundlewires by the tension on the tie wire which the rotating bundle must drawoff as it is coiled about the bundle. This twist together with theapplication of the tie wire to hold the bundle wires firmly in twistedposition will produce in the finished bundle greater compactness andrigidity than has heretofore been attained.

As bundles of wire are ordinarily placed in, piles on a floor, or inracks having only theireye ends exposed to view, I have secured theinformation tag on the end of the bundle in order that the informationcontained thereon could be observed without moving the bundles. Thebundle as an article of manufacture is not claimed herein but forms thesubject matter of a copending application Serial No. 47,084.

While I have shown my invention in but oneform, it will be obvious tothose skilled in the art that it is not so limited, but is susceptibleof various changes and modifications, without departing from the spiritthereof, and I desire, therefore, that only such limitations shall beplaced thereupon as are imposed by the prior art or as are specificallyset forth in the appended claims.
